Abstract
Extensive application of pesticides especially fungicides for crop production resulted in adverse consequences such as resistance development in pathogens and environmental pollutions. An alternative approaches in agriculture are requisited for environmental sustainability. Hence, an investigation was conducted with medicinal plants like Adhatoda vasica and Acalypha indica to exploration antifungal compounds to inhibit the growth of post -harvest pathogen as Colletotrichum capsici in chilli fruit. Ethanolnic and methanolnic of extract of leaf and stem of Adhatoda vasica and Acalypha indica by using soxhlet to study the effect on chilli Colletotrichum capsici. The pathogen, C. capsici was isolated from the infected part of fruit surface of chilli. Aqueous, 70 % ethanolic and methanolic extract of Adhatoda vasica and Acalypha indica were screened, against C. capsici. The colony diameter of control and extract treated fungus was measured with the help of scale to determine percentage growth inhibition of fungus. Conidia germination inhibition carried out at Minimum inhibitory concentration (MIC) and Medium inhibitory concentration (IC50) of ethanolic and methanolic extracts. The leaf and stem extracts of Acalypha indica extracted in the ethanolic solvent expressed higher antifungal activity than aqueous and methanolic extract. Conidial germination percentage inhibition was reported 90.38 % at MIC concentration of A. vasica leaf extract of ethanolic followed by ethanolic stem extract of A. vasica, Methanolic leaf and stem extract of A. indica, respectively. Appressorium formation in C. capsici was inhibited completely at MIC concentration of ethanolic leaf extract of A. vasica, but the delay was observed by methanolic extract of leaf and stem.
